Subject [jira] [Comment Edited] (LUCENE-7157) Geo3DPoint implementation should pay attention to the ordering of lat/lon points

Hi Robert,

Yes I think the terminology is confusing, so perhaps we already agree.  If the outer polygon
is always "clockwise" that effectively establishes the choice of what is inside and outside,
and this works for me.

> The LatLonPoint API implementation pays attention to the order of the points; "clockwise"
means one side of the polygon boundary, and "counterclockwise" means the complement.  We need
to use that in Geo3DPoint and convert into whatever the underlying GeoPolygonFactory method
requires.
